Populations are also found in montane and highland environments at higher elevations.

Range

Distributed across Australia, India, Indonesia, Japan, and Philippines. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Common thrips

Habitat

Typically found in virtually all terrestrial and freshwater habitats.

Range

Found across Europe (5 countries) and North America (United States).

Common Seahorse

The common seahorse is found in tropical and temperate waters. Males carry and deliver the babies.

Common thrips

<em>Aptinothrips rufus</em>, the common thrips, is a small insect in the order Thysanoptera, family Thripidae, recorded from five European countries including Denmark, Norway, and Sweden, as well as the United States. It is Not Evaluated on the IUCN Red List. This species is primarily a grass-feeding thrips, found on grasses and grassland vegetation across temperate regions. The name "rufus" refers to the reddish-brown coloration of adults. Like other thrips, adults are minute insects, typically 1–2 millimeters long, with fringed wings adapted for flight and dispersal across grass habitats. Populations can be locally abundant in grasslands during warm summer months. <em>Aptinothrips rufus</em> feeds by piercing plant cells and extracting sap, primarily from grass blades and stems. It typically completes multiple generations per year under favorable conditions. The species has limited direct agricultural significance compared to some other thrips pests, but plays a role in grassland ecosystems. Biological traits such as precise body weight, longevity, and egg production figures remain poorly documented in standardized scientific assessments.
